Ultra-pure water equipment is a core water treatment device in industries such as electronics, semiconductors, pharmaceuticals, and laboratories. Its long-term stable operation cannot do without scientific maintenance and care.Yuanlai Water TreatmentDrawing on years of technical experience, we share practical maintenance tips to help keep equipment efficient, extend its service life and reduce operating costs.

1. Conduct regular inspections to promptly identify potential hazards

Before starting the machine every day, check the raw water pressure, the quality of the incoming water, and whether the displays of all instruments are normal. Also, inspect the pipelines and valves for any leakage or abnormal noise, and ensure the stable operation of the pump body. During operation, the conductivity, resistivity, flow rate and pressure difference of the produced water should be closely monitored. Any abnormal data should be promptly investigated to prevent minor issues from evolving into major malfunctions.

Ii. Regular maintenance of the pretreatment system

Pretreatment is to protect the reverse osmosis membrane.EDI The key to the module. Quartz sand filter per 1-2 Backwash once a week to remove silt and suspended solids and prevent clogging. The activated carbon filter is backwashed monthly.3-6 Replace the filter material every month to ensure the removal effect of residual chlorine and organic matter. The water softening equipment should be regenerated regularly and the salt level in the salt tank should be checked regularly to prevent the resin from failing and causing scaling. Precision filter element 1-3 Replace it once a month to prevent impurities from entering the core components at the back end.

Iii. Reverse Osmosis MembraneRO"Fine maintenance

Reverse osmosis membranes areUltra-pure water equipmentThe core requires focused maintenance. Control the quality of the incoming water on a daily basis to prevent water with high turbidity, high residual chlorine and high hardness from entering. Regularly flush the membrane elements under low pressure before the machine stops every day 5-10 In minutes, wash away surface contaminants; every 3-6 Chemical cleaning should be carried out once a month, and a dedicated cleaning agent should be selected based on the type of contamination to restore the membrane performance. Overpressure, idling without water, and long-term shutdown without maintenance are strictly prohibited. If the machine is shut down for a long time, protective fluid should be injected and sealed.

FourEDI Module specification maintenance

EDI The module directly determines the quality of ultrapure water and requires standardized operation. Control the stability of the influent water quality to ensure the resistivity and hardness of the influentTOC Meet the standards; Regularly check the pressure difference, current and voltage of the module to avoid overloading operation. Monthly EDI Carry out a cleaning and maintenance to remove surface scale and impurities. If the machine is to be shut down for a long time, power should be cut off, accumulated water drained, and proper moisture-proof and dust-proof protection measures taken.

V. Maintenance of Electrical and Auxiliary Equipment

Regularly inspect auxiliary equipment such as water pumps, fans, valves and instruments, and carry out lubrication, tightening and anti-rust treatment. Keep the electrical control box dry and clean, remove dust regularly, and check whether the circuit connections are firm to avoid short-circuit faults. The backup power supply should be tested regularly to ensure the safe shutdown of the equipment in case of sudden power outages.

Scientific maintenance is the guarantee for the long-term operation of ultrapure water equipment.
